transact! is async, so to get the effect you want you will either need a synchronous transaction or local state - sync tx is mentioned here https://book.fulcrologic.com/#Inputs32 and in the docstring https://github.com/fulcrologic/fulcro/blob/develop/src/main/com/fulcrologic/fulcro/raw/components.cljc#L415
this pattern applies if you want to use local state:

Thanks @U051V5LLP, your answer prompted me to try to reuse that component again, after reading the documentation you linked. In the end I was able to make it work even without local state nor sync transactions on the fulcro part. Turned out my error was simpler, but I learned a lot! In particular, when would you reach for sync transactions?
oh nice! Mainly for dealing with inputs. Reagent also has to deal with this: https://github.com/reagent-project/reagent/blob/master/doc/ControlledInputs.md https://github.com/reagent-project/reagent/blob/master/src/reagent/impl/input.cljs
